iv been telling you's sun does nothing... and to much sun is bad for the lips... the skin burns easily and blisters.. sorry to hear about you going back to school with this shit i know it sucks!!! im still strong headed on some form of exzma or autoimmune disease its not normal that the cells keep dyeing off and continual shedding... contstant moisturizer is the key to treating the symptoms and if ya lucky it might just go.. in regardss to one thing at least you dont get that white gunk of line that form in the inner lips especially on the top lip! that shit frustrates me the most out of anything..
